Review on LASFIT 44mm Canbus Error Free LED Festoon Bulb 561 562 564 567 - 400LM 6000K Extremely Bright Xenon White (Pack of 2) - Ideal for Trunk Cargo Light & License Plate Bulbs by Carl Durant

Like: Alive like crazy. Dislikes: They are not compatible with the Wireball butt and will not work in the 561 (Wireball) mount. If the heatsink wasn't so heavy (well designed) it could hang just fine, but given the two pin contact the light just falls off so the LED bar is pointing towards the roof and not down. Let's see if I can use more than one of these. My Chevy PU now has a nice bright light but it's the only place in my fleet of 6 cars/trucks where I can use it. I used them in my dome light on an '87 Jeep. Finding this solution will involve a pair of suitable 561 lamps.
